To all whom it may concern.-

Be it known that I, Inn J. Wnrxnnno, a citizen of the United States,anda resident of Chicago, county of; Cook, and tate of Illinois, haveinvented certain new and useiul lmprovements in Processes for Formingand stutling Compartment-Mattresses, of which the following is a'full,clea'rpandv exact description.

The invention relates to processes for forming and stu'fiing compartmentmattresses and-eonsits in the ieatures of improvement hereinafter setforth and more.

particularly pointed out in--the appended claims. i

In the drawings which illustrate a ma chine for carrying out theimproved process, Figure l is a plan view illustrating the manher offilling the compartment mattress and in which a portion of the mattressis broken away. Fig. 2 is a cross-section on the line 2-2 of Fig. 1.Fig/8 is a partial plan View of'the machine showing the sec compartmentmattress.

'tional carrier: in retracted position. Fig. i is a perspectire viewpartly 1n section of a In iorming an ordinary mattress, the tickmg ofcotton fiber or the like, and the filling material is then placed-undercompression and is held in place by tufting the mat tress, i. 6., byconnecting the opposite side Walls of the ticking by tufting stitches Ina compartment or tuftless mattress, the 0pposite side Walls of theticking are connected along parallel lines-to form a series of long,narrow compartments extending be-f tween the opposite side edges of themattress and such compartments are subsequently stufied or filled, andin such constructions, the filling material is held under compressionand against displacement within the narrow compartments. 7 Inasmuchasthe' mattress is not tufted, after it is filled, the material must beinserted within the narrow compartments under considerable pressure, so

the same. Heretofhre such compartment mattresses have beciii stufied byfilling one pm-ting uprights 3. The horizontal andlonpresent invention,

is filled with material, such as layers vember 10, 1911, SerialNo.661.410. as to snugly and compactly fill 7 puckered over .a row ofspouts which are spaced apart'to receive the portions of the tickingwhich separate the eompartments bet veen them, and the charge of fillingmaterial is compressed and is deposited within the compartments by meansof a sectional carrier which 1s adapted to be projected through the rowof spouts.

In the drawings, Fig. *1 illustrates one form of coin 'iartment mattressin which theopposite side walls "1. are connected togetherat the edgesof the mattress by edge walls 6, and between the edge Walls by .a seriesof partition walls 0, these partsbeing formed of suitable fabric. Theconnected partition walls serye the place of the ordinary tuftingstitches tohold the filling material (Z under pressure and againstdisplacement. But, of course, the partition'walls cannot be placed inposition after the mattress is filled, but must be sewed to the sideWalls along the lines 6 before the filling material is placed in theticking. Preferably, the partitions c and the compartments extendtransversely of the mattress between the side edges thereof andv theticking is firstconr pletcd, except that the ends of thecompartincntsare left open at one of the side edges. The ticking is then preferablypuckered. over a row of spouts which are spaced apart to admit thepa'rtitionso between them. The

divided into sections Within a suitable sec-- tional carrier and thelatter is then advanced through the spouts andinto;the compartments ofthe tick to simultanebusly de posit all of the com-pressedsectionsjoftheI charge Withinthe same. a

By preference,

the sectional carrier is-mechemically operated. -The drawings illustratea machine which is set forth and claimed in an application filed by meNo- The body of this machine is mounted on a frame comprising side bars1 connected by cross bars 2 and mounted 'upon suitable supgitudinalcrossbars l and 2 support a floor or bed 1 and vertical side Walls 5,the latter beingfixed to posts (3 that extend upwardly from thehorizontal side bars '1. The bet vided with flaring inner ends.

and side walls 5v form-a box-like body for receiving a-charge of fillingmaterial sufiicient to com )letely fill the mattress.-

A horizon al series or row of spouts are arranged at one end of thebox-like body.

These spouts are preferably rectangular in section and have topand'bottom walls 7 and- 8 and opposite vertical sidewalls 9. The. spoutsare spaced apart from one another, as,

" to the posts 6 at the adjacent end of the ma chine frame. The spoutsare also preferably braced and held in position by a bar 11 whichextends between the. end posts 6 and which extends over and is securedto the inner portions of the topwall 7 of the row of spouts.-

The bed plate Fl of the boxdike body is preferably provided with a.sheathing 12 of .sheet metal, and this sheathing is preferablyextendedthrough the spouts'and over the bottom walls 8 thereof, as shown in Fig.2. 5

Thespouts are of such size and are so spaced apart that the compartmentticking, ,when puckered overthe same. fits snugly thereon with thepartition walls a between the spouts. The inner open endportion oftheticking is preferably clamped to the spouts by a'pair of bars 13which extend transversely above and below the spouts and "are connectedby a series of bolts 14 arranged between the spoutsand'having thumb nuts15 on their upper ends.

The sectional carrier comprises a sliding cross-head or bar 16 which ismounted upon the floor or bed 4 between the side walls 5. Upper andlower sets of thin flexible presser boards are connected' to the slidingcrosshead or bar 16. The lower presser boards 17 are fixed to the bar 16and the upper presser boards 18 are connected thereto by hinges 19. Theupper portions are arranged in line with the lower boards, so that thecarrier is divided to correspondwith the transverse row of spouts and tothe compartments of the ticking. When the carrier is advanced,onepair-:01 boards is adapted to pass throughcach of the spouts, asindicated in Figs. 1 and 2.

The sectional carrier is -meehanical1y driven hyconnecting the cross bar16 to a pair of drive chains. In. the form shown. these chains 20 extendover sprocket wheels 21 on shafts 22 at opposite ends of the machineframe. The'upper portions of the chains pass through slots 23 formed inthe bed 4 and are connected to the cross-head 16 realises by bolts 24.In the form'shown, the shaft 22 at the front" end of the machine isprovided with a large s rocket 25 which may l e driven in oppositedirections from any suit' 'able source of ower. Whenthe sectional. as

carrier is comp etely withdrawn from. the spouts, the upper sets ofprcsser boards 25-. can be raised and the entire charge of fillinmaterial is plac'md within the box-like bod;-- of the machine upon thelower boards 12".

--Theupper boards are then lowered to coin .formed in brackets 28 fixedto and project in upwardly from the side walls 5. Prefer ab y, also, anadditional pressure roller 29 as arranged adjacent the inlet ends of thespouts.

The charge of material isdivided into sec time either before or as it isadvanced'inti" the ticking. In the machine illustrated, a my series ofcircular knives- 30 are mounted upon a cross shaft .31 that isjournal'ed at it end in suitable brackets rising from the side bars 1 ofthe machine frame. These knives are ar'rangedin line with the v shapcdthe at fiectors 10' between the inner ends of the. spouts and theloweredges of the knives ex tend through slots 32 in' the machine. firsterably, also, as shown, the pressure roller is provided with notches 33kc clear th edges of the knives. The shaft 31 is rcvided at one end witha pulley 34 on w icl: passes a belt 35. By this means the knives arecontinuously rotated during the opera tion of the machine. p

In carrying out the improved process, the compartment ticking is firstcompletely formed. as described. except that the'com partments are leftopen a'lont', orient the side edges thereof. The ticking is then drawnoverand puckered upon the transiuuei. row of'spouts with thepartitions'o between 1 the spouts. The pressure rollers 25 are thenremoved an'dthe upper boards 18 of the sectional carrier, which haspreviously been i s withdrawn. are raised and the charge of materialsufficient to stuff the entire mattress placed within the box-like bodyof the ma chine. he upper-presser boards are their. lowered lo compressthe charge and the rollers 26 are replaced into position to hold thecharge under compression, and the sectional carrier is then advancedtomove the presser boards through'the spouts and into the courpartmentsof the ticking. The charge is di-' vided into sections, either bytherotary cutters 30 as it is advanced or, before it is advanced. by aidof the longitudinal partition hoards arranged within the box-like bodyof the.maohinc frame. As the sections of the teem throu h walls l "ofthe charge. Furthermore, the 'flarin deflectors atrthe inner ends of theside we ls-of the spouts serve to separate and compress the sections of:the charge.in lateral direcllfrtion.v Preferably,however, the pressureis relieved to some extent upon the sections of the charge as they passfrom the spouts? As e the; sections of i the charge make their exit fromthe"s puts, they will expand laterally,

since they are confined against lateral; exl pension only by thesidewalls of the'spouts.

Furthermore, as the presser boards refthin and flexible-theexpansive-tendency of the compressed filling material willspring thefree ends of the boards apart, as indicatedin Fig. 2 of the drawingsandthus', in a, measure; permit the charge to expand verti- ,"celly.This expansion of the charge sections I cannot .ihtehfre \vith'theproper filling of, .25 thecompartments. since by pucke'ring'the tickupon the spouts; the charges are deposited inthe extreme inner ends-oftheir 'com-- i artments as they emerge from the spouts;

80 they are deposited within the compartments of the ticking,"isadvantageohs, since .itis necessary to relieve the pressure on thecharge before theeseetional carrier is withdrawn.

- pletely inserted within thecompartments-of the ticking. the fillingmaterial will have'exp a nded along its side edges sufiiciently toengage the partition of the ticking with 40 sufficient friction toprevent the charge sec: tions being 'withdrawn with the clamping boards,this action heingassisted by the springing apart of the clamping'boardsat 1 their free ends thereby not only relieving. the pressure to permitthe "withdrawal" of the carrier whileflth e charge is' frictionally vsustained in place, but permittingthe simulv taneous withdrawal of I allportions of the carrier. This avoids complichtion of-mech- 6'0 anismwhich Would-be reqir'lred -if it was. necessary-to withdraw the carrier;portion- -carrier and of the charge are advanced the spouts, the; upperand lower and-8 of-the latter engage the upper.
